Specification of Letters Patent.

Application filed November 6, 1908. Serial No. 461,334.

To all whom 'it may concern:

Be it known that I, EDWIN BURHORN, a citizen of the United States, and aresident of Hoboken, in the county of Hudson and State of New Jersey,have invented certain new and useful Improvements in By-Passes, of whichthe following is a specification.

My invention belongs to the same class, and has in general the sameobjects, as described in my Patent No. 900,479, dated October 6th, 1908,which may be briefly stated as follows:

7 My invention is an improved by-pass, to Y be used 1n connectlon with ameter, or any where it is desirable to cut in, or cut out the meter orapparatus at will. In my present invention 1 have attained .theseobjects with simpler apparatus than that described in my patent referredto; I-have also introduced some improvements, tending to make theapparatus more accessible for cleaning and repairs. 4

Referring now to the drawings in which similar figures refer to similarparts. Figure 1; is a horizontal section on line ww Fig. 2 of myby-pass, applied to a water meter. Fig. 2; is an end elevation of Figs.1 and 3. Fig. 3; is a horizontal section of my by-pass on line ww ofFig. 2, showing the controlling plug in a diiierent position from that.shown in Fig. 1. The meter is not shown. Fig. 4; is a horizontal sectionon line yy' Fig. 5 of an alternate form of bypass, attached to a Watermeter; the latter being partly broken away. Fig. 5; is an elevation ofFig. 4, the meter being omitted. Fig. 6; is a part section on line 41-41Fig. 4. Fig. 7 is a part section on line b-?) Fig. 4.

Fig. 8; is a part section on line 00 Fig. 4.

Fig. 9; is a part section on line a'a Fig. 4, after plug is rotated.Fig. 10; is an isometric view of the valve plug.

' In detail; 1 is a meter casing, inclosing the space 2, in whichrevolves the impulse wheel 3, actuated by a tangential current of fluidentering through the passage 4, and leaving by the passage 5. The formof meter shown, is known as a current meter; one of the displacementtype would be equally applicable.

Integral with, or rigidly attached to, the

casing 1, is the valve body 6, containing an inlet passage -7 and anoutlet passage 8 and interior passages 9, 10, 11. Rotatable within thebody 6 is the taper plug 12, containing the ducts 13 and 14.

To operate the meter, the plug 12 is turned to the position shown inFig. 1; the fluid enters at 7 then by plug duct 14, body passage 10, andpassage 4, enters the space 2, rotates the wheel 3 and leaves by thepassage 5; then by passages 11 and 13 the outlet 8 is reached, and thecycle is complete.

To bypass the meter, the plug 12 is turned to the position of Fig. 3, inwhich it will be observed the passages 10 and 11, giving access to themeter casing are closed; the flow being diverted to the passage 9 in thebody '6; thus cutting out the meter, without stopping the flow in themain line.

With the plug in position of Fig. 3, the meter may be disconnected atthe fiange'15, for cleaning, adjustment or repairs; without in any wayinterfering with the flow in the main line.

While the meter is in operation, the plug 12, may be locked in position,by the bar 16 attached to same; the lug 17 integral with the body 6;and'the padlock 18, connecting the bar and lug, thus preventingtampering with the by-pass when attached to the meter or otherapparatus.

In the alternate form ofby-pass, a cylindrical plug 19 is employed,similar in principle to those in use on Corliss engines.

A valve body 22, inclosing the rotatable plug 19; has an inlet 20 andoutlet 21, also interior passages 23 and 24, connecting with thepassages 4 and 5 of the meter casing 1. The plug 19 has a bearing strip25 extending its full length on one side, and a concave part 26, dividedby the partition 27 into two chambers 28 and 29. In the concave back ofthe chamber 29, is the opening 30, communicating with the duct 31. Theplug is rotated by the T piece 32, extending through the stuffing box 33in the usual way.

When the plug is in the position shown in Figs. 4, -5, (S, 7, and 8, themeter is in the circuit. The fluid enters at 20, thence into the space31 in the plug; passing through the opening 30 it enters the chamber 29,communicating with the passage 4 of the meter, through the passage 24.After leaving the meter by passage 5, it enters passage 23, opening 1ntovalve chamber 28, which.

Patented Nov. 23, 1909.

to the position of Fig. 9, where it will be observed the bearing strip25 closes the passages 23 and 24:, (23 not bemgshown being directly backof 24,) so shutt ng ofi communication with the meter; at the same time.the duct 31 registers withthe two passages 20 and 21, thus ermittingfree passage of the fluid from in ct to outlet.

The plug may be locked in position by means of the bar 34 connected tothe T lece 32; the lug 35 integral with the valve liody 22, and thepadlock 36, connecting the bar and lug; as clearly shown.

The meter may be discoimected at the flange 15 when desired.

A valuable feature hereof is in having the meter or other apparatus onthe one hand and the bypass valve casing on the other hand attachableand detachable from each taining in its walls fixed separate inlet andoutlet passages for connectlon to a lpe l1ne,

and fixed separate supply and ischarge passages for connection to anapparatus to be served, (as ameter) in combination with a movable valveseated in the hollow of said valve body and containing duct portions so-.;ar'ranged with relation to said passages that when the valve is inone position the flow will be in order through the inlet passage, thevalve, the supply passage, the said tipparatus, the discharge passage,the valve, and the outlet passage, and when the valve is in a secondposition the flow will be through the inlet passage, the valve, and theoutlet passage, with the supply and discharge passages and saidapparatus cut ofi. and a meter comprising a casing, and inlet and outletpassages (as 4 and 5), with said meter casing detachably secureddirectly to said valve body so that said meter inlet and outlet passagesregister respectively with said valve body supply and dischargepassages.

2. In a by-pass a hollow valve body containing in its walls fixedseparate inlet and outlet passages for connection to a pipe line, andfixed separate supply and discharge passages for connection to anapparatus to be served, (as a meter) in combination with a movable valveseated in the hollow of said valve bodyand containing duct portions soarranged with relation to said passages that when the Valve is in oneposition the flow will be in order through the inlet passage, the valve,the supply passage, the said aparatus the dischar e assa e the valve andthe outlet passage, and when the valve is in a second position the flowwill be through the inlet passage, the valve, and the outlet passage,with the supply and dis charge passages and said apparatus cut ofi;

and an apparatus to be served havin an "said apparatus, 4th an outletpassage for connection to said pipe line, 5th an outlet from said by-wapassage, and 6th an inlet thereto; in com ination with a rotatable valveseated in the hollow of said body and containing two ducts so arrangedthat when 'in one position one duct connects said inlet passage and saidsupply passage, and the otherduct said discharge passage and said outletpassage, whereby when the valve is reversed the inlet and outletpassages will be both connected to said by-way assage and the saidapparatus will be cut 0;.

4. The combination of a by-pass valve and an apparatus (as a meter), thetwo being detachable and attachable and when attached being in directcontact with each other, the said apparatus being designed with a casinghaving inlet and outlet apertures in its wall, and a long interiorpassage within its casing wall for bringing said apertures'closetogether on the casing wall, and the by-pass having supply and dischargepassages corresponding in location with sand inlet and outlet.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on the 2nd day of November, 1908.

EDWIN BURHORN.
